ATEX rated computers, tablets and mobile phones have made inspection, testing and site operations much more time efficient since their introduction to the market place in recent years. 

No longer does data have to be collected in the field then returned to the control room or office to be analysed.  Todays products have the data storage and diagnostic tools to enable engineers and technicians to get real time data on operational and maintenance issues whilst remaining active on the plant or in the field.

Here at Exloc we offer a comprehensive range of products for both Zone 1/ 21 and Zone 2/22 based on diverse platforms and technologies which are suitable for most clients, site requirements and of course budgets.

For instance, we have both Windows10 and Android (5.1.1 to 7.0) tablets which are suitable for use in Zone 1/21.   Android tablets for use specifically in zone 2 / 22 only are also available and are normally more cost effective.

We also have a range of ATEX approved cases which enable non-certified standard products, including iPhones, iPads and Android devices to safely be used in the hazardous area.  Some of these products can be fitted by the customer but the majority require fitting by the manufacturer to confirm that the products have been installed correctly and certification is adhered to.

Our portfolio of mobile phones are based on the Android 4.4-6.0 platforms and range from simple mobile phones right through to SmartPhones with dual integrated cameras for use in Zone 2/22 environments.

A whole separate range offering the same benefits is available for clients requiring higher certified Zone 1/21 compliant products specifically.

Continually Evolving SIL Relay Range now complemented by a New GMI Surge Protection Units

Exloc Instruments UK Ltd are the sole UK distributor of GM International products who continue to expand their range of SIL certified relays and switch repeaters designed and engineered to meet the requirements of modern niche projects.

Part of the new range of DIN rail mounted and field mounted surge protectors from GMI which protect 4-20mA HART, Digital I/O, World FIP and Fire & Gas signals and we hope to expand on this soon.

Meanwhile, the switching of Safety-Related circuits demands the use of specific SIL certified Relay Output modules, capable of delivering the highest rate of availability and functional safety.   The original SIL relay by GM International was the D5293S, a relay output with a normally energised load and with load and line diagnostics which achieves SIL3 according to IEC61508:2010 Ed.2.

The new D5294S and D5295S modules are both 4Amp modules (normally open and normally closed contacts respectively) which again achieve SIL3 and are suitable for Normally Energised or Fire & Gas /Normally De-energised load with open/short circuit diagnostics.

Both modules also provide full Load & Line Internal Diagnostics: load voltage and current, load resistance (patented), leakage from load to earth, coil integrity and internal faults.  Moreover, MODBUS communication allows the units to be remotely interrogated and configured.

Hardware is SIL 3 certified, while diagnostic functions are now also SIL 2 certified by TUV: they remain two independent features, which can be used separately or together.

All models are ATEX, IECEx and SIL certified and are suitable for installation in Zone 2 / Div. 2 Hazardous locations.

The range of GM International modules which are SIL capable continues to expand and also includes the single channel D5093S and dual channel D5093D Loop Powered Switch Repeaters.  These modules operate at 24 to 220 Vac/Vdc and are suitable for safety related system applications requiring SIL 3 in high risk industries.

Each channel is able to reflect the presence of a 24 to 220 Vac/Vdc input signal to the output by closing an optically coupled Normally Open open-drain transistor (solid-state relay, MOSFET output).

Mounting of the units can be via standard DIN-Rail or on customized Termination Boards, in Safe Area or in Zone 2, group IIC T4.  All models are ATEX, IECEx and SIL certified.
